Application led March 13, 1925. ,Serial No. 15,411.

- This invention relates to the mounting of instruments onl anv instrument board and more particularly to the mounting of units in whichare combined a plurality of indicating mechanisms or controls adapted to ydisclose and control theworking conditions of various elements of an automobile.A Y

Anobject of the invention is tok provide a single assembly of several instruments which can be attached to another instrument for securing them to the instrumentr board or dash of an automobile. f In the form shown in the drawings, .the -instruments are secured to two plates which are held in position on the back of the instrument board by a bracket attached to an instrument, shown as the speedometer, said speedometer extending throughand engaging the opposite face of theV instrument board. Y

The above and other objects and features of the invention will be apparent from the following description of the illustrated embodiment shown in the accompanying drawings, in which:

Figure 1 is a board showing thereon;

front view of the instrument the instruments mounted Figure 2 is a detail of the'plate to which the instruments are attached,

Figure 3 is a detail of the bezel plate; Figure 4 is a rear view of the instrument board` showing the instruments mountedv thereon; v

Figure 5 is a sectional View on line 5-5 of.

Figure 4;.and

Figure .6` is of Figure 4.

Referring to the drawings illustrating one practical embodiment of my invention and particularly to Figure 1, the instrument board 11 is shown provided with openings 13 and 15 adapted to receive the assembled instrument units 17 and 19. Another open-l ing 21 is adapted to receive the'instrument 23, shown asa speedometer. f y

An instrument plate 25, shownrin Figure 2, isV provided with a depressedv portion 27 and openings 29 and 31.- Clips' 33, shown as stamped out from the body portion of the plate, secure the instruments, such as an ammeter 35 and oil gage37, to said plate in such amanner that their-face is visible through the respective openings 29 and 31.

a sectional View on line 6-'7-*6 f A bezel plate I39, shownv in Figure 3,.'is

preferably nickel plated and when lattached p to the instrument plate 25,y by means of the clips 41, a neat appearing construction is obtained. The instrument plate25 isfpref# erably finished in black enamel and when the` nickel plated bezel plate is attachedV thereto the same appearance is obtained as when the bezel 43 is formed on the face plate and ,the center portion carefully enameled leaving Lthe bezel nickel plated; It has been found that the method of attaching the bezel tothe face plate in this manner, for the purpose of contrast, is less, expensive than the usual methodofv enamelling the center within the bezel. It willbe understoodV that various contrastsfother .than the black enamel and nickel platingmightbe` used.

A switch 45and choke 47 are mounted on a plate 25 which is similar to the plate 25 with the exception that the center isv adapted to receive the switch and choke. A bezel plate 39 is applied torthe .front :tace of the plate 25 in the same manner as the same plate 39v isy applied to the `plate 25, above described. 4, y V'The instrument plate 25, instruments 35 and 37 and bezel plate 39, when assembled, form the instrument unit 19; and the plate 25', switch 45, choke 47, and bezel 39 form the instrument unit 17. These two unitsfare of the clamp bars 51 and is provided with slots 57 and an opening 59 to receive an extension 61 of vthe speedometer through' which vthe drive shaft extends. The two bars and the Ushaped bracket forma frame construction which secures the instruments to the instrument board.

It will be noted that the construction thus far described comprises a unit consisting of the instrument units 17- and 19, clamp bars 51, `and bracket 55, which is' all bench assem-v bly and one which can be readily mounted on they instrument board. In mounting the instruments, the speedometer 23 is insertedV from the front, of the instrument board through ythe opening y21. A lange 63 onthe speedometer, engages the front face of the instrument board and forms an abutment for determining the position thereof. The instrument unit is then placed on the back t the instrument board in such a manner that the two bezels enter the openings 13 and l5. Screws 65 on the speedometer enter the slots 57 and the nuts 67 enga-ge the outer face of the bracket 55 holding the assembled unit and speedometer in position on the instrument board. d

Vhile one illustrative embodiment of my invention has been described in detail, it is not 'my intention to limit its scope to that particular embodiment shown except as indicated by the appended. claims.

What claim is:

l. In combination, a traine, a plurality of instruments carried by said trame, an instrument board having openings therein, an instrument extending through one ol' said openings and having an abutment engaging oneA of the surfaces of said instrument board, and attaching means carried by said instrument, said frame engaging the opposite surface of said instrument board and beingsecured thereto by said attaching means.

2. In a device of the class described, an instrument board having a plurality of openings therein, av plurality et instruments adapted to be received in said openings from opposite sides of .id instrument board, and means carried by one ot said instruments for securing all 'of said instruments to said instrument board.`

` In a device of the class described, an instrument board, a plurality of instruments mounted on said "instrument board, and means carried by one of said instruments for securing the other instruments to said instrument board. Y n Y 4. In a device of theclass described, an instrument board, a centrally displaced instrument mounted on said instrument board,

two other v instruments located one upon either side of said central instrument, and means carried by said instrument for securing said other instruments to said instrument board. Y

5. In a device or" the class described, an instrument board, a frame comprising a bracket having upper and lower outwardly extending bars, instruments mounted at the ends of said bars, and means for attaching said frame to another instrument having an abutment engaging the opposite side of said instrument board.

6. In a device of the class described, an instrument board having openings therein, a frame comprising a bracket having outwardly extending arms, instruments mounted on said arms, an instrument 'having Van abutment engaging oneside of said instrument board and extending through one ot said openings, and means for attaching said frame on the opposite side of said instru-V ment board to said instrument.

7.. An instrument assemblyl comprising an instrument board, a bracket adapted to be supported from said instrument board, separate face plates secured to each end of said bracket, an instrument secured to one side of each face plate, and a bezel plate secured to the opposite side of each face plate.

In testimony whereof I affix my signature.
